Problems solved by technology

[0008] Therefore, using existing wireless communication methods to transmit and store a large amount of video data without effective information will cause a great waste of bandwidth and storage resources
The unstructured storage method also makes the realization of intelligent retrieval more difficult

Embodiment 1

[0035] Such as figure 1 Shown, a kind of segmented video transmission method comprises the following steps:

[0036] S1: The sender identifies and extracts the foreground object in the original object image, and then sends the background image of the object image to the receiver.

[0037] The original target image is collected by the camera equipment. Since the premise of the application of the band-based video transmission method is that the background of the shooting picture is fixed within a certain period of time, the acquisition mode of the camera equipment can be a fixed acquisition mode and a fixed-range periodical change acquisition. acquisition mode or irregular change acquisition mode in a limited range; fixed acquisition mode, that is, the camera equipment is fixedly installed and the shooting angle is always the same. The background of the picture captured in the fixed range periodic change acquisition mode changes periodically within a certain range. For example...

Embodiment 2

[0054] The motion foreground of video data contains almost all valuable information. For example, in the application of abnormal event monitoring, the occurrence of the event only occupies a very small amount of monitoring time, and most of the monitoring objects are the foreground of moving targets. . In the mobile video call scenario, the human face is the most important information carrier, and the change of the picture is the change of the facial expression. Therefore, in such scenarios, changes in video images can be abstracted as changes in specific semantic information. Therefore, the following takes indoor monitoring and mobile video call scenarios as examples to describe the band-segmented video transmission method in detail.

[0055] In indoor surveillance scenarios, people are usually the most common moving foreground target and the main object of surveillance. Human behavior is manifested in movements, which depend on the activities of joints. Therefore, the dec...

Abstract

The invention provides a bandwidth-saving video transmission method. According to the method, video data are deconstructed into text semantic information at a sending terminal to realize textualized transmission of key information; and the text semantic information is constructed into a reconstructed image consistent with the semantic information of an original target image at a receiving terminalbased on an image generation technology. Therefore, different forms of computing capabilities are given to each part in the communication network structure; specifically, a mode of endowing a sendingterminal with a video data feature semantic computing capability and endowing a receiving terminal with a semantic generation image computing capability is adopted, and an original local centralizedcomputing communication mode is converted into a cooperative diversity computing communication mode, so that the bandwidth and storage resources are greatly reduced, and the transmission, storage andretrieval efficiency is improved.

Description

technical field [0001] The invention belongs to the technical fields of feature extraction and image generation, and in particular relates to a method for segmented video transmission. Background technique [0002] In the IT3.0 era of ternary interconnection of man-machine-things, tens of billions of intelligent terminals and hundreds of billions of object devices will be produced. They will be integrated into various application fields such as education, transportation, industry, agriculture, production, and entertainment. With the continuous improvement of people's demand for communication, video communication has gradually replaced voice as the basic carrier of communication content. A large number of devices will communicate based on video. [0003] Video services in traditional industries such as surveillance and automobiles are gradually being networked, and the continuous emergence of new video service forms such as webcasts, short videos, and AR / VR has caused a sur...
